If you want to remove those collections, open the config file, remove or comment out [add `#` to the beginning] any or all of those lines under `collection_files`, and delete the collections manually from Plex.
TV Shows and other libraries work the same way as you've seen above. Create a section under `libraries:` in the config.yml, refer to default files or create a collection file, define collections, run the script.
The command in this walkthrough will run all collections and libraries immediately. If you want to modify that behavior to run just one or some collections, or just one library, or just overlays or the like, review the [Run Commands & Environment Variables](../../environmental.md).
These things are all generally defined in collection files that are referred to in the config file. The starting point for creating these files is [here](../../../files/collections.md).
